Double chin
The contour of your chin and neck gradually blurs, and your face looks rounder and heavier in profile photos, even though your weight hasn't changed much.
What is a double chin?
A double chin is fat that collects under the chin, making the lower face look rounder and heavier, and the line between chin and neck no longer clear. Many people think it's only about weight, but that's not entirely true.
Some quite slim people still have a double chin because their body tends to store fat there. Others don't have much fat, but the skin under the chin has slackened with age, creating the look of a second chin. Most cases are a combination of both.

What causes a double chin?
Fat under the chin
- ConstitutionSome people tend to store fat under the chin, even when they aren't overweight.
- Weight changesWeight gain, even a little, may show first in the chin area.
Skin & supporting tissue
- AgeingDeclining collagen and elastin make skin less firm, no longer holding the fat beneath in place.
- SunlightUV rays break down collagen faster, speeding up laxity.
Habits
- PostureLooking down at your phone and sitting hunched for long periods make the under-chin area look fuller.
- LifestyleLittle sleep, salty food and little exercise make fluid retention and fat more visible.
Common types
A thick layer of fat under the chin. Needs treatment to refine superficial fat combined with skin firming.
Skin has lost elasticity and sagged. Needs collagen stimulation and tightening of the skin's layers.
Both fat and lax skin. Needs a multi-layer plan, sometimes combining two technologies.
Where should I start?
Everyone has a different cause and degree, so the most important thing is to understand your condition correctly before choosing a solution.
During your Da Ký™, we assess whether your double chin is mainly due to fat, lax skin or both, the thickness of the fat, the skin's elasticity and the overall contours of your face. Only then do we choose the right technology and number of sessions.
Home care
No exercise or product melts fat under the chin, but daily habits make a big difference to how visible a double chin is.
Good posture, enough sleep and a low-salt diet reduce fluid retention in the lower face and help treatment results last longer.
Recommendations we often give
- Mind your posture. Hold your phone at eye level and sit up straight. Habitually looking down makes the under-chin area look fuller.
- Sunscreen on the neck too. The skin of the neck and under the chin also needs sunscreen every day to slow laxity.
- Eat less salt, sleep enough. Less salt in the evening and enough sleep help limit fluid retention in the lower face.
- Keep your weight stable. Constant weight gain and loss stretches the skin and makes it hard to firm up again.

In-clinic options
At Claire, a double chin is treated with technologies that act on both superficial fat and skin firmness at the same time, without surgery.
Skin Tightening uses Exilis Ultra 360technology, combining RF and ultrasound in the same treatment head. Precisely controlled heat refines superficial fat under the chin while stimulating collagen so the skin firms up. The treatment is gentle, with no downtime.
For a double chin with very lax skin or a less defined jawline, Focus360 combines UltraLift focused ultrasound acting on the SMAS muscle layer with RF microneedling (VFRM) that renews the dermis, tightening and clearly redefining the chin and neck contour.

Other options and advice
For very thick fat under the chin, or very lax skin after major weight loss, invasive methods such as liposuction or surgery may give better results. If that's the more suitable option for you, we'll say so clearly and refer you to the right specialist.
Claire always follows ethical medical aesthetic practice: we only recommend what truly suits you.
